AUTOMATIC WATER-FEED FOR POULTRY.

To all whom it may concern Be it known that I, HARRY L. DAVIS, a citizenof the United States, residing at Saratoga Springs, in the county ofSaratoga and State of New York, have invented certain new and usefulImprovements in Automatic -Water-Feed for Poultry, of which thefollowing is a specification.

My invention relates to apparatus for automatically regulating thesupply of water from a holding receptacle, to a drinking receptacle,designed to be used by poultry.

An important object of my invention is to provide apparatus of the abovementioned character, which is so constructed that a large quantity ofwater may be held in a tank or barrel, and a small quantity of the samesupplied to the poultry drinking receptacle or pan, in an automaticmanner, as the water level therein is lowered by the water being drunkby the poultry.

A further object of the invention is to pro vide apparatus of the abovementioned character, which is so constructed that the same cannot beoperated by the poultry except by the same drinking the water whichresults in a lowering of the level thereof.

A further object of the invention is to provide apparatus of the abovementioned character which may be adjusted so that different depths ofwater may be constantly main tained in the drinking receptacle or pan.

Other objects and advantages of this invention will be apparent duringthe course of the following description.

In the accompanying drawing forming a part of this specification, thefigure is a side elevation of the complete apparatus, parts thereofbeing shown in central longitudinal section, for the sake ofillustration.

In the drawings, wherein is illustrated a preferred embodiment of myinvention, the numeral 1 designates a water holding or supplyreceptacle, which may be either a tank or barrel, the same beingpreferably vertically arranged and supported by any suitable means.Connected with the lower end of the preferably vertically arranged waterholding receptacle 1 is a preferably horizontal feed pipe 2, havingscrew-threaded connection at its free end with a T-coupling 3. ThisT-coupling, at its upper end, has screwthreaded connection with apreferably vertically arranged pipe 4, receiving a valve rod or link 5therein.

The numeral 6' designates a relatively large Specification of LettersPatent.

and heavy valve, formed of iron or the like, having a cylindrical bodyportion 7 and a tapered or conical upper portion 8, decreas ing indiameter upwardly. Connected with the upper end of the conical portion 8is a link 9 receiving a link 10, whereby the valve 6 has a free pivotalconnection with the rod 5. The valve 6 has a conical end 11, decreasingin diameter downwardly. The conical end 11 is adapted to enter atubularvalve-seat 12 having screw-threaded engagement with the lower endof the T-coupling 3, as shown. The upper end of the tapered end 11 issu'l'liciently large to fit snugly within the bore of thetubular-valve-seat 12. The tubular-valve-seat 12 has its upper endtapered to provide an annular knife edge 13, which engages the lower endof the cylindrical portion 7 of the valve 6, when the valve is seated.The function of having the tubular-valve-seat provided with the knifeedge 13 is to provide means for preventing the accumulation of sedimentor deposits upon the lower end of the valve 6, the tapered end 11serving to remove deposits from the inner wall of the tapered knifeedge, by slidable engagement therewith.

Connected with the upper end of the vertical pipe 1 is a bracket 14, towhich is pivoted a vertically swinging lever 15, having one end thereofpivotally connected with the upper end of the valve rod 5, as shown at16. Pivotally connected with the opposite end of the lever 15, as shownat 17, is an operating rod 18, the same being provided with a turnbuckle 19, whereby its length may be increased or decreased. Connectedwith the lower end of the T-coupling 3 and extending laterally therefromis a horizontal arm 20, apertured for receiving the reciprocatoryoperating rod 18. At its lower end the rod 18 has pivotal connection, asshown at 21, with an arm 22, which is attached to oneend of a verticallyswinging float 23. Connected with the opposite end of the float 23 is anapertured bracket 24, receivingthe horizontal arm of an L- shapedsupporting rod 25, to be pivotally connected therewith. The vertical armof the L-shaped supporting rod 25 extends through an opening 26in thearm 20, and is screw-threaded for receiving clamping nuts 27, disposedupon the upper and lower sides of the arm 20. The vertical arm of thesupporting rod 25 does not have screwthreaded engagement with the wallof the opening 26, and the same is raised and lowered by propermanipulation of the clamping nuts 27. It is thus seen that by raisingand lowering the supporting rod 25 and adjusting the length of theconnecting rod 18, the depth of the water level in the pan or drinkingreceptacle )8, receiving the float 23 therein, may be permanentlyregulated. Attention is called to the fact that the float 23 isadvantageously located directly beneath the coupling 3 and pipe 2, thesame being thus protected, whereby the apparatus cannot be operated bythe poultry except by them drinking the water.

In the operation of the apparatus, when the water level in the drinkingpan or receptacle 28 falls below a predetermined depth, the float 23descends, drawing operating rod 18 downwardly, which in turn swingslever 15 to elevate valve 6. When the valve 6 is elevated or unseated,the water passes from the holding receptacle 1 through pipe 2 anddischarges into the pan 28, such discharge continuing until the desiredwater level is restored, at which time 7 the valve 6 is automaticallyreturned to its closed or seated position, as 1s obvious.

5, to wit, the fact that said valve is free to partake of independentlateral move- 'ments, whereby the tapered end 11 thereof my invention, I
